Have you ever wondered how a tornado would look like from above the cloud? Well, it would look like a typical supercell (i.e. not really like a hurricane with a big hole in the middle). This animated gif shows really weall how it looks like (as a time-lapse) when storms pop-up over a few counties.
Notice how they burst out over a line and how the anvil spreads out. You can also see an overshooting top on a few of the storms showing that these are quite powerful storms. Pretty cool, huh?
